itinp- I In existing separating machines-for milk,

it is known to strain the milkeither before the latter is poured into the reservoir of the separator or at the actual moment of pouring The obj ect of this straining is to separate any impurities fromthe-milk' In the case of whey it is known generally that, as a consequence of the previ0ustreat ments it ha's-undergone, it is emulsified and that a deposit of froth is formed inthe reser voir evenafterstraining, which froth Very I diflicultto removeQfThls froth is'not re tained, by any screen. a

The object of the invention to remove this disadvantage arrangingthe strainer, in the case of whey, at thebottom of the reservoir insuch a Way that the froth formed by I thej moment'ary standing "of the emulsified milkis formed above said strainer. t

Inthe case of a non-emulsified milk (good milk) the strainer may be placed at the upper part ofthe'reservoir of the separator.

According to the invention, the strainer] proper is placed atthelovverpart'of a con tainerhaving solid walls. a This container has oneof its dimensions (length or width) smaller than that of the corresponding part f' thereservoirbf the separator so as to be capable of being placedeither at theupper' .part of the latter or inthe base by: partly f svvingingthe said container.

" it The accompanying drawings illustrate'by way of example andin a non-limitingm'an- I ner one embodiment of the invention; the latter includ ng the various featureswhich the arrangement illustrated comprises.

' Figure lisaperspective view with parts in section of a separator reservoir and a str'ainer according to the invention. 7 f j Figures 2 and 8 are diagrammatic views in which the container is shown". at the lower part ofthe reservoir and-.in its'position of engagement respectively;

The separator reservoir2, generally situmeant the upper part of the separator, is

provided with a duct 2a which per'mitsthe strained milk toflow towards the turbine." I The strainer 3, locatedatthe lower part of;

the solidgwalled container 3a, :may be situ.

, therefrom.

ated at the upper part of the said reservoir 2 by means of flanges t With which the said" container is provided. r

In order to be placed at the bottom of the reservoir 2 (Figure 2) the said container is in Figure, 3) and bears against the reservoir by means of feetBb of small height. This. insertion into the reservoir is rendered pos-' sibleon' account of the difference in length" between the reservoir proper and thecontainer 3a.

It goes without'sa-ying that the container In'the. case when'whey is being strained, I g H the froth which is formed remains practically entirely in the container 3a. By simply removing the container, the whole of the frot formed can be Withdrawn.

What I claim is:-f f

1. Adevice for straining emulsified mill; before being poured into the reservoir of a separator, embodying a, receptacle comprising a sieve or strainer, itself serving as the ceptacle being substantially the same as those otthe reservoir, and one of said dimensions i the receptacle, its introduction into the reservoiror ts withdrawaltherefrom.
